Data Summit Consulting — database performance work rooted in Kota Kinabalu

We help product and platform teams tame slow SQL, bloated execution plans, and connection storms through scoped reviews and ongoing advisory—not shelfware audits.

Serving Sabah, Peninsular Malaysia, and remote engagements across ASEAN time zones.

When East Malaysia latency is not the whole story

Teams in Kota Kinabalu often inherit schemas written for a single region, then watch nightly ETL or mobile API traffic stall once data volume crosses a quiet threshold. Index hints and bigger VMs buy weeks, not quarters.

Data Summit Consulting pairs on-site working sessions along Jalan Lintas with remote screen-shares so your DBAs and backend engineers keep ownership of the fixes we recommend.

Typical starting points

PostgreSQL or MySQL workloads with p95 query times drifting upward
Read replicas that lag during Sabah business hours
ORM-generated SQL that bypasses covering indexes
Migration cutovers where rollback plans need rehearsed timings

Infrastructure you already run—tuned where queries meet disk and memory.

“We schedule deep-dive blocks around Kota Kinabalu business hours so your on-call engineers are awake when we replay production-shaped workloads—not at 3 a.m. on a borrowed VPN.”

— Lim Wei Jie, proprietor

How we pair with your team

Execution-plan clinics

We capture representative queries, walk through EXPLAIN output line by line, and document rewrite options your team can regression-test in staging. No black-box “optimised” scripts shipped without context.

Clinics work well when you already have metrics but lack a shared vocabulary between application developers and database administrators.

Advisory retainers with clear boundaries

Retainers reserve a fixed number of hours each month for plan reviews, index hygiene, and incident post-mortems. Scope letters spell out what is in and out so finance and engineering leads align before work starts.

Questions teams ask before booking

Do you need production access on day one?

We start with anonymised plans, schema diagrams, and metrics exports. Read-only replicas are enough for most first sessions; elevated access is requested only when a finding needs live verification.

Which engines do you cover?

PostgreSQL, MySQL/MariaDB, and SQL Server are our core focus. We document unsupported engines honestly rather than improvising on unfamiliar internals.

Can work happen entirely remote?

Yes. Many clients outside Sabah prefer remote blocks. We still anchor milestones to Malaysia business hours for overlap with your staff.
